  14. Research • Useful to research application and problem. • Use computer trade journals, reference books, and Internet (including user groups and bulletin boards). • Provide information on how others have solved similar problems, plus whether or not software packages exist to solve, or even partially solve, the problem.

  15. Questionnaires • Conduct surveys through questionnaires – special-purpose documents that allow facts to be gathered from a large number of people while maintaining some control over their responses. • Two types of questions, namely free-format and fixed-format.
